【Important】 Statement regarding Unity Runtime (UnityPlayer) security vulnerability CVE-2025-59489

This update contains a fix for the recently-discovered Unity Runtime (UnityPlayer) security vulnerability, CVE-2025-59489 .Due to external circumstances, we are locked to using a specific version of the Unity SDK (2021.3.40f1/6fcab7dbbbc1) — however, please rest assured that despite this fact, our automated build process now automatically patches the CVE security vulnerability at build-time, and the game is safe to have installed on your device.We have also reissued patched builds for our other Unity game, Summer at the Edge of the Universe.For more information, please refer to Unity’s official developer documentation on this matter: https://unity.com/security/sept-2025-01As always, thank you for supporting Studio Élan.

Regarding older versions of the game

※ For those who choose to use older versions of the game via the "Betas" tab, please note that at this time of writing, 1.x versions of the game have not yet been retroactively patched. (※ 2.0 has been patched.)Please remain patient as we set up the infrastructure to reissue new, patched builds of these old versions.
